FIELD: food industry.
SUBSTANCE: method involves fruits pouring with 85°C hot water during 2-3 minutes, with subsequent replacement of the water with 85°C syrup. Then the jars are sealed, put into the carrier ensuring mechanical air-tightness of the jars, sequentially heated in a 130°C air flow at a rate of 1.5 m/s during 14 minutes and showered with 100°C water during 6 minutes with subsequent stage cooling in baths with 80°C water during 4 minutes, with 60°C water during 4 minutes and with 40°C water during 5 minutes; during the whole process of heat treatment the jars are turned upside down with a frequency equal to 0.133 s-1.
EFFECT: invention allows to reduce the process duration, preserve natural components of the raw material applied, reduce boiled fruits quantity, enhance nutritive value of the ready product, prevent thermal breakage of the containers, intensify the heat-exchange process and simplify the heat treatment process.
